Our Verdict

Bang & Olufsen Beoplay H9 Gen 1 Wireless

Bowers & Wilkins PX Wireless

The Bowers & Wilkins PX Wireless are a slightly better headset than the Bang & Olufsen Beoplay H9 Gen 1 Wireless. The Bowers & Wilkins have stronger noise isolation, which makes them a bit more suitable for both loud and quieter conditions like commuting or being at the office. They also have a slightly more premium-looking build quality. On the upside, the Bang & Olufsen have an easier-to-use and more casual design than the Bowers & Wilkins. They also pack more bass and have a customizable sound profile, which feels lacking in the Bowers & Wilkins' app support.
